  • 1 cup sugar Adds sweetness and a shiny, crackly top.
  • 2 large eggs Provides structure and fudgy body.
  • 1 cup cocoa powder Adds chocolate flavor.
  • 1 cup flour Holds the brownies together.
  • 1 teaspoon vanilla extract Enhances chocolate flavor.
  • 1 pinch salt Balances sweetness.
  • 1/2 cup chocolate chips Optional; folds into the batter for pockets of melted chocolate.

Frosting

  • 1 cup chocolate chips For making the frosting.
  • 1 tablespoon cream To make the frosting smooth.
  • 1 tablespoon butter For the frosting.

Toppings

  • 1 cup rainbow candy chips For the signature cosmic look.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper, leaving some overhang.
  • Melt the butter and let it cool slightly.

Make the Brownie Batter

  • In a large bowl, stir in sugar into the melted butter, then add eggs one at a time and mix in vanilla.
  • Add cocoa powder, flour, and salt, then stir just until no dry streaks remain. If using chocolate chips, fold them in.

Bake

  • Pour the brownie batter into the pan and smooth the top. Bake for 22 to 28 minutes, checking for doneness after 20 minutes. The center should be soft.
  • Let brownies cool completely in the pan.

Make the Frosting

  • In a microwave-safe bowl, combine chocolate chips, a splash of cream, and butter. Heat in short bursts, stirring until smooth. Adjust thickness with more cream if needed.

Frost and Add Toppings

  • Spread the frosting evenly over cooled brownies and immediately sprinkle with rainbow candy chips.
  • Chill the pan for 30 to 60 minutes to set the frosting before slicing.

Notes

Make sure not to overbake the brownies. For variations, you can use gluten-free flour, dairy-free substitutes, or reduce sugar for a healthier option.
